IMPROVEMENT IN HORSE HAY-FORKS.

Tha Schedule referred to .in these Letters Patent and making part of the same.

Be it known that I, J osnrH H. BnnvroN, of Thornbury, Chester county, Pennsylvania, have invented an Improved Hay-Elevator; and I do hereby declare the following to'be afull, clear, and exact description of the same.

My invention consists, first, in the use oian adjust-` able ball or enlargement upon the operating-rope of specification, and in which- Figure lis a side view of my improved hay-elevator, anc

Figure 2, the same, as it appears when thrown open discharge a load. The apparatus consists of two rods or bars of metal, A and A', crossed and jointed at a, and so bent at their lower ends as to form curved jaws, between which a mass of hay maybe held; while the upper ends of the said bars are straight and nearly parallel when the jaws are closed, as shown in iig. l.

The apparatus is suspended by a rope, B, which passes through slots c c, at the upper ends of the bars A and A, and beneath pulleys (l d, arranged to turn in the same, one end of the said rope being'secured to some stationary object at b, and its opposite end passing over a'pulley, a', and thence to the point from which the-apparatus is to be operated. The rope passes also through a hole, e,fin the outer end oi' an arm, F, which is jointed to the jaw A ofthe elevator, and connected to the bar A by a cord, h, which passes around a pulley, i, attached to the said bar.

lhe rope B is provided with a knob or ball, H, ar-' To load the apparatus,the jaws are spread apart, and forced downwards into the hay to be elevated, that portion of the mass contained between them being seized and securely held, when the jaws are closed together in the act of raising the apparatus.

When the mass of hay held between the jaws has been elevated to almost the desired point, the ball H, previously adjusted upon the operatingrope, passes through the slots c c `of the apparatus, and strikes the arm F, being, as before described, too large to pass through the opening in the same.

The rope is still drawn over the pulley x, in the direction of the arrow, iig. 2, and the arm F, against which the ball H bears, is turned back from the apparatus, until the cord h, which previously hung loose, is tightened; after which, on continuing the pull upon the operating-rope, the jaw A and upper end of the bar A will be drawn towards each other, and the centre of gravity of the apparatus suddenly shifted, it then hanging nearly perpendicularly from the pulley fr, as shown in fig. 2,'with the jaws completely opened,

and the mass of hay discharged.

By merely readjusting the ball H, the apparatus can be made to discharge at any point, being entirely automatic in its action, and by its use I am enabled to dispense with the usual unloadingsdevices and operatingcords, which render ordinary hay-elevators complicated and diflicult to manage.

I claim as my invention, and desire to secure by Letters Patentj l. The use of'an adjustable ball or other enlargement upon the operating-rope of a hay-elevator, for automatically unloading the same, substantially as herein set forth.

2. The combination of the adjustable ball H with an arm, F, jointed to one ofthe jaws of a ln y-elevator, connected to the other by a cord,"h, and having. an opening, c, for the passage of the operating-rope, the whole being constructed, arranged, and operating substantially as and for the purpose described.

In testimony whereof, I have signed my name to this specification 'in the presence of two subscribing wit- W'itnesses:

ADnIsoN MAY, WM. WHITEHEAD.
